WATER HEATER.

Applieation ined october 2s, 1920. 'serial no. 418,975.

To all whom. t mag/jconcern:

Be it known that I, ARTHUR N. Ronn'rs, a citizen of the United States,residing at Chicago, in the county of Cook and State of Illinois, vhaveinvented certain new and useful Improvements in Water Heaters, of

which the following is a specification.

This invention relates to vwater heaters, and the primary object of theinvention is to provide an improved water heater for domestic purposes,which is adapted to be incorporated with any type of heating stove, sothat the necessity of providing a separate heating device for water iseliminated, thereby resulting in a saving` of fuel, said heater being soconstructed as to permit a circulation of warm water through the waterpipes at all times, thus preventing` the freezing of the pipes in coldweather.

Another object of the invention is to proA vide a water heater of theabove character which is of exceptionally simple and durableconstruction, one that can be easily kept in repair, one that is simpleto manufacture,

and one which can be placed upon the market at a reasonable cost.

With these and other objects in view, the invention consists in thenovel construction, arrangement and formation of parts as will behereinafter more speciiically described and claimed, and illustrated inthe accompanying drawings forming a part of this specification, in whichdrawings:

Figure 1 is a side elevation of the coil used in the water system.

Figure 2 is an elevation of the same looking in the direction indicatedby the arrow in Figure 1.

Referring to the drawings in detail, wherein similar referencecharacters designate corresponding parts throughout the several views,the letter C indicates the improved heating coil which will bepositioned in a stove of a suitable construction so that water passingfrom a tank through the coil and back to the tank may be heated in theusual manner.

The coil C is of a special construction, and is so formed that the watercirculating therethrough will be heated instantaneously and this coil isplaced directly within the stove in the usual manner. This coil includesa lower loop 10 having the spaced legs 11 and 12,. The legs 11 and 12are connected together in spaced relation by means of a U-coupling 13.Arranged above thelower loop 10 is an upper longitudinally extendingpipe141 which is arranged above anddirectly between the legs 11 and 12 sothat the/heat from the lire in the stove will readily ilow between thelegs and against the pipe 141s. This pipe lei is connected with the leg`11 which is formed relatively long lby means of a Ucoupling 15. It canbe seen that this U-coupling 15 is inclined so as to position the pipe14 in between the legs 11 and 12. The opposite end of the pipe 14 isconnected to an L-coupling 16 by means of a U-coupling 17 as clearlyshown in the drawings. The inner end of the leg 12 has also connectedthereto an L-coupling 18. The L-couplings 1G and 18 are arrangedsubstantially in vertical alignment and form the means for con nectingthe coil with the tank from which the water is drawn and after beingheated returned.

The improved coil C. may be assembled and placed directly in the stoveabove the grates thereof and the outlet and inlet pipes l19 and 2Orespectively threaded into the elbow couplings 16 and 18, or shortlengths of pipes may be connected to these elbows and extended throughthe wall of the stove and connected to the pipes 19 and 20.

By this construction it can be seen that the coils can be readily andeasily associated with any type of stove. The size of coil is determinedby the quantity of water de sired, and by the size of the stove withwhich it is associated.

It can be seen that the cold water will flow from the lower end of thetank through the pipe 20 into and through the coil and then be returnedto the tank through the pipe 19 in a heated state.

From the foregoing description, it canv be seen that an exceptionallysimple and durable water heater has been provided, which can beincorporated with any heating stove and which is of such a constructionVthat hot water can be instantaneously had.

Changes in details may be made without departing from the spirit orscope of this invention; but,

I claim:

1. In a water heating unit the combination of a single loop disposed ina horizontal plane comprising long and short spaced parallel legsconnected by a U-shaped coupling, a second loop disposed in a verticalplane immediately above the space between lll) the legs of the lirstmentioned loop and comprising long and short legs, means connecting theend of the longer legs of the first and second mentioned loops oppositeto the ends to which the shorter legs thereof are respectivelyconnected7 and inlet and outlet conduits respectively connected at thefree ends of the shorter legs of the lirst and second mentioned loopsand extending` transversely of the parallel disposition of the legs ofsaid loops.

f2. A compact Water heating unit comprising a single loop disposed in ahorizontal plane comprising long and short parallel spaced legsconnected by a Ushaped coupling, a single loop disposed in a verticalplane immediately above the space between the legs of the firstmentioned loop and also comprising long and short legs, a couplingconnecting the longer legs oi both of said loops at the ends of saidlonger legs opposite those ends to Which the shorter legs of the loopsare connected, the longer leg of the second loop being shorter than thelonger leg of the first loop whereby to terminate short of the couplingof the iirst mentioned loop, and inlet and outlet con duits respectivelyconnected in a vertical plane at the free ends of the shorter legs ofthe first and second mentioned loops and extending in line at rightangles to the legs of the said first and second mentioned loops.
